Beyond energy savings and comfort, YKK invites visitors on regular
facility tours and uses graphic-based
data from their building energy
management system (BEMS) to communicate the value of energy and
water reduction strategies. Another
innovative feature is a state-of-the-art, real-time earthquake detection
system designed to provide immediate response and safety information
for occupants. The entire building
rests on seismic isolation pads.

ing the design phase. Additionally,
experiments were conducted with
subjects in a mock-up research laboratory to verify comfort in areas using
the slight airflow (Figure 7).

The mock-up research and lab
experiment, with over 150 participants,
confirmed comfort in over 75% of the
participants using higher temperature
setpoints with a slight airflow, demonstrating compliance with ASHRAE
Standard 55-2013 (Figure 8).

Innovation

The real innovation of the YKK80

building was in meeting the challenges brought forth by the 2011

disaster and the entire owner,
design, and construction teams’
commitment to use an integrated
design process in response. The
key innovations include: the

Operation and Maintenance
